HIS ATTORNEYS Patented Nov. 22, 1932 PATENT OFFICE LEWIS W. CONNEL-L, OF .TOLIET, ILLINOIS DOOM .Application filed January 23, 1932. Serial No. 588,467.

This invention relates to certain novel improvements in looms, and has for its principal object the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture. 7 It is an object of this invention to provide .a novel, efficient, and relatively inexpensive device operable by the beater of the loom informing a weaver of the heddle operating scheme he must follow and which heddles he must next operate to produce a preselected pattern in the fabric.

Another object of the invention is to provide an improved device for facilitating, and

avoiding mistakes in, the threading of the heddles.

A further object of the invention is to provide a novel and inexpensive pattern dial and support therefor; and to provide new and .20 efficient means for rotating said dial support step by step from the movement of the beater.

An additional object of the invention is to provide operating means for the pattern dial support which are ineffective except when the beater is moved to the full limits of its beating stroke. 7

Another object of the invention is to provide means operable by the beater of the loom for informing the weaver when he must insert binder threads into the fabric.

Other objects of the invention are: to provide a device for promoting accuracy and avoiding mistakes in weaving withhand and treadle looms and to provide means for facilitating the teaching of weaving.

' Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to behereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, showing the preferred form of construction and in which:

Fig. 1 is a fragmentary front elevational view of a conventional loom showing my invention associated therewith; 7

Fig. 2 is a side elevational view on line 2-2 in Fig. 1; v

Fig. 3 is a fragmentary top plan View;

Fig. 4 is a fragmentary side elevational view of the invention;

Fig. 5 is a sectional view on line 5-5 in Fig. 3;

Fig. 6 is a sectional View on line 6--6 in 5 Fig. 4;

- Fig. 7 is a fragmentary side elevational view of the pattern dial and indicator on line 77 in Fig. 6; and

Fig. 8 is a fragmentary detail View of the threading dial.

In the drawings, which illustrate a preferred and practical embodiment of the in vention, 10 indicates a loom frame, on which are mounted a warp roll 11, fabric roll 12, beater 13, and pivotally mounted heddle frame operating handlevers 14 from which are suspended by flexible elements 15 heddle framesl6 in which are arranged heddles 17, all of which aforementioned structure is of conventional design and, therefore, may be replaced by other equivalent structures. Thus, for example, the invention to be described hereinafter may be applied to a threadle-operated loom instead of to a hand loom as shown.

Fast to a rotative shaft 18 on the frame 10 (Fig. 6) is a dial-supporting ratchet disc 19 to which a step by step motion is imparted, by a pawl 20, as the beater 13 is operated, where y to impart a step by step motion to the pattern dial,-such as 21 or 21a, Figs. 7 and 8, which will be explained more fully hereinafter. Motion of the beater 13 is imparted to the pawl 20 and ratchet disc 19 as follows: The pawl 20 is carried by an arm 22 of a frame 23 which is pivotally mounted on the shaft 18 (Fig. Attached to an arm of the frame 23 is an upright connecting rod 24 which is pivotally connected (Fig. 5) to .a pivotal lever 25 which carries a cam roller 26 that is guided in a cam slot 27 'formedas a part of a pivotal cam plate 28. The cam plate 28 is connected to the beater 13 by a horizontal connecting rod 29.

Each time the beater 13 is pivoted or moved a short distance (two inches) from its extreme right hand position (Fig. 2), the connected rod 29 pivots the cam plate 28 to the right (Fig. 5) causing the roller 26 on lever 100 to be raised by the cam slot 27 on the plate 28 and thereby raising the lever 25 and the vertical connecting rod 24 which in turn pivots the frame 23 on the shaft 18; causing the pawl 20 to impart a step by step move ment to the dial-supporting ratchet disc 19 for reasons now to be explained.

The indicia on the dial 21 (Fig. 7) inclicate or represent numerals arbitrarily given the heddle frame operating levers 14 (or treadles in a foot power loom) and which are to be depressed to raise the heddle frames 16 to produce a preselected pattern; each.

of the rows 30 and 31 representing the heddle frame raising scheme for one particular pattern. Each time the beater 13 is moved a short distance (two inches) from its extreme right hand position (to the left, Fig. 2) the ratchet disc 19 and dial 21 thereon are moved. Every other time the heater is moved a short distance (two inches) to the left (Fig. 2) a circle (4) (Fig. 7) registers with pointer or indicator 32 and thus indicates the numbers of the levers 14 to be depressed. When the dial stops in a position wherein the pointer 32 is half way between two circles then the levers 1 and 3 or 2 and 4 are always depressed. This scheme remains constant regardless of the pattern used. The'dial, of

course, moves every time the beater moves to the left (Fig.2) providing the beater starts from its extreme right hand position (Fig. 2) and is moved two inches or more. For this reason any number of short strokes can be made with the beater at the other end (left hand end, Fig. 2) without moving the dial.

The dials 21 are detachably mounted on the ratchet disc 19 by means of a retainer plate 33 that is mounted on a threaded stem 34 of shaft 18 and any desired number of circular pattern rows 30 and 31 may be provided on a binder thread which always follows a pattern thread. In weaving a pattern on a loom employing my invention, binder threads are inserted at those times when pointer 32 registers half way between two circles such as 30 which are spaced on dial 21, which happens every other time the dial moves. The weaver knows that he uses levers or treadles 14 in a pro selected scheme depending on whether the binder is being inserted from right to left or left to right.

If more than one stroke of the beater 13 is required to make the fabric firm several short strokes can be made without moving the dial 21 because of the dwell 36 in cam slot 27 which is ineffective to raise the roller 26 until the roller passes out of the dwell 36 in cam slot 27 Another use of the invention is in the threading of the heddles 17 and to indicate the numbers and succession of the heddle frames 16 to be used in threading the heddles I provide a dial such as 2141 which may be mounted on shaft stem 34 in the manner hereinbefore described for dial 21, so as to register with pointer 32. When this dial 21a is mounted on the shaft stem 34 the disc 19 may be rotated by hand independently of the beater 13 by disconnecting bar 29 from beater 13 and using the bar 29 as a handle for operating the ratchet disc operating means; or a. handle may be connected to the bar 29 for use during the heddle threading operation; the numbers on dial 21a representing numbers arbitrarily given to the heddle frames 16 and corresponding operating levers 14.

On each heddle operating lever 14 is a lug 37 (Fig. 1) which, when a lever 14 is depressed to raise a heddle frame'l6, engages in a notch 38 in a pivotal latch finger 39 whereby to latch the heddle frame 16 in raised posi-, tion. The latch fingers 39 are all simultaneously released from the lugs 14 on the heddle frame operating levers 14, when the beater 13 is moved a short distance (one-half inch) from its extreme right hand position (Fig. 2), by a cam roller 40' (Fig. 5) which rides over the face of a cam plate 41 attached to the vertical connecting rod 24; the cam roller 40 being carried by an arm 42 which is fast to the shaft 43, to which the latch fingers 39 are likewise fast, whereby upward movement of cam plate 41 against cam roller 40 rotates arm 42, shaft 43 and fingers 39 (clockwise Fig. 4) and thereby releases the notched portions 38 of latch finger 39 from the lugs 37 of heddle frame operating levers 14, thus releasing and lowering the heddle frames 16.

Among the advantages of my invention as hereinbefore described are: it eliminates mistakes on the part of the weaver in threading the heddles and in weaving; it increases the weavers speed; it facilitates teaching weaving; and improves generally the efiiciency of a hand power or treadle loom.
